We often use advice handed down from family and friends when it comes to skin care, but some of that advice is actually bad for your skin. We look at some of the more popular myths and the truth behind them.

1. Cellulite creams are effective in removing cellulite. Topical creams and lotions do not “zap” away cellulite, but may help your skin look smoother for the short term. Causes and treatments for cellulite have long been debated, but most experts tend to agree that exercise and nutrition play a role in reducing the appearance of cellulite.

2. You don’t need sunscreen on a cloudy day. Believe it or not, up to 80 percent of the sun’s UV rays can penetrate through clouds. Sunscreen is still needed on days even when the sun is on hiatus. And contrary to what you may think, sunscreen is also needed on a cold and cloudy winter day.

3. Makeup with SPF is all I need to protect my skin from sun damage. Experts say you need to wear a sunscreen with a SPF of at least 15 to maximize sun protection, something you will not get by using only makeup with a SPF. You would have to apply a large amount of makeup to have the level of protection that a typical sunscreen provides. Makeup with SPF is a nice compliment, but should never be used instead of sunscreen.

4. Drinking plenty of water will give you great skin. While water has many benefits for overall body health, simply drinking 8 glasses a day will not reduce wrinkles or give your skin a makeover. Water plays a crucial role in keeping the body properly hydrated, which does help skin tone, but water alone does not address all of your skin care needs. You still need to take care of your skin with proper cleansing, moisturizing, sun protection, sleep and nutrition.

5. Tanning beds are safer than sun. This is still up for debate depending on who you talk to, but most medical experts say “no”. Any type of regular exposure to UV rays without protection can cause skin damage and in some cases, cancer. Artificial tanning can also be more dangerous for people who easily burn. Achieving that sun kissed glow either in the sun or a tanning bed damages the skin and causes premature aging and wrinkles.
